MULTIPLE GRADUA'NG MH'INE.

Application mea october 15,

ylhis invention pertains to' inachines adapted to mark spaced graduatio'ns on a plurality of vessels or containers at the saine time, and itis intended more especially, but not re'sti'ic'tedly, ior use in appliances oi' this character for the graduation of glass measuring" vessels, such as graduates. 1

The lead-ing object, or prime aim, of the invention, which is an improvementon: that of United states Patent No: 1,463,317, granted to' me July 31, 1923, is the production ol a niafzhine k i this character which will graduate the vessels `with" great accuracy und with an effective" saving of time over the employment of other appliances otl thel saine general character.

lVliereas the principles of construction and inodes of operation of the invention are capable of satisfactory use in a machine graduating a plurality ot vessels simultaneouslysome o'l' them, nevertheless, may be separately and advantageously employed in mechanisms graduating one' vessel at a time. Another if attire of invention resides in the I'nailzing simultane'ously of several vessels with figures or' numerals corresponding" to certain ones the graduation lines, the preferred embodiment of the invention having nieans whereby such iigure's are subject te adjustmentor variations asv to size. In order te, enable these skilled in this art' to have a 'full complete understanding of the intention, both from structural and functional standpoints, in the accompanying drawings, forming apart o't this specilic'atio'n, and throughout the several views of which like reference characters have been Y, employed to designate'v the saine elements, l have illustrated a desirable' and preferred embodiment of the' invention, which aceon'i'plislit's the above-stated and other desirable advantages.

in these drawings: Figure 1 is a side elevation 't the iinprored and iiovel inaliin with certain of the parts broken away from clarity ot' ilhistratiozn, but this view,- nevertheless, indicates most of the more o'i less important parts of thev construction. In this view seine oli the' levers and other elements are broken away, whereas some 'of the other 1924. semi N. 74326941 parts vare indicated somewhat diagraminatically. The' inclined, slidable carriage is in a' psiton correspondiiig to about the tenth or twelfth graduation line.

`Figu1re 2 is a front view ot the' machine with certain parts of the mechanism in the background omitted and a' portion or' the nuniber'i'g device broken away. The holding appliances of the two end vessels to be ,Graduated are' shown more or less completely in this ligure, while the intermediate ones have' been siiinp'liiied for olearness of illustration.

n Figure 3 is a plan view of the screw driving mechanism', which feeds the carriage, at the rear of themachine and shows the trip device which releases the screw-feeding devices to allow an idle stroke' thereof during the marking of each tenth graduation line or ring` around the vessel undergoing graduation.

Figui-e 15 ieiades'iour, perspective views of the correspondinn number of canis controllingT the action of the grlufluating;l or marking scriber, and these canis, although illustrated as separated from one another, are in the saine relative positions as when held together in their plate.

Figures 1G, 1T, 18 and 19 are diagrammatic views indicating,r the various positions which the cam-plate and its cams assume, Figure 16 illustrating the position the plate takes when the machine automatically stops, the upper cani being then in the path of the roller controlling the operation of the graduation line scriber.

Figures 20, 21, E22, 23 and 24 illustrate `the numbering' mechanism; Figure 2O beingr an elevation, Figure 21 ay plan view,` Figure a fragmentary detail on line 2Q of Figure 20, Figure a horizontal section of line 22S- Q3 on Figure 20, and Figure 2&1 a ver tical section of the line 24 of Figure 21.

Figures 25 and 2G are two `views of opposite sides of the finished graduated product.

Referring to these drawings it will be perceived that the machine includes a inainframe 30 of irregular shape conveniently supported on suitable legs or feet` 3l.

B v reference to lFiniture/s 1, 2, 8, 9 and 12 it will be seen that the front ot the machine includes a pluralityY of upright, intermediate bars 32, 32 and corresponding' end-bars 33, 33, spaced apart to provide six (6) vertical channels between them, the machine, in this particular instance, being adapted to `graduate sin vessels or receptacles at the same time.

Inasinuch as the vesselsu1niorting construction is the saine for each of? the several containers to be gradua-ited, a complete descrillition of one Will sutlice for all. Each ot these `vertically-disposed bars and 3?) has registerinteT grooves Sil, receiving;

`the marginal parts oli' a plate 35, each ol the latter havingr on one 'lace a longitudinal dove-tail rib 36.

Annpper block 4l. and its associated clamp-plate 42. slidable aloner each rib 256, and ma;Y be clamped or fastened in an)7 desired adjusted position bv means oi screws la as will be readily understood. i

Flach such lneniber ll equipped with a stud atl on which a bent arin 45 is rockinirlv anointed, the arru at. its tree :forward end being apcrlured and receiving a vertical sleeve i1-6, the latter accommodating the c v liudrical hub all? of a slide clamp 4S having a beveled recess 49 adapted to accommodate the flaring base 51 of an inverted, glass graduate or other vessel 52 to be graduated in this machine.

The reduced-diaineter shank 53 of such stem 47 or body 48 extends through an apen ture in the end of shell or sleevedand is externally equipped with a stop-nut 54,

A coil. expansion spring' 55 encirclcs the shank oil. bearing at its lower end on the shoulder at the junction of parts 47 and 53 and pressing at itsupper end against the inner face of the end of the shell 46, thus vieldingly pressing clamp 48 down against the top ol base 51 ot the glass vessel 52.

A spring-pressed hell-crank lever 56 is fulcruinelfl on arn'i 45 at 57, one arni oi such lever forming' a handle, the other arin hav ingr tivo notches 58 and 59 adapted to cooperate `with a lug 61 outstandingr from the block 41.

`When the notch or recess 59 accoininodiites the lug, as shown in lzligrure 12, the arm 45 and its clamp t8 are heldin'the operative position infflicated` in .such figure,` but when the arm l5 and the vessel clamp are rocked upwardly about the axis H into an inopera` tive position releasing; the vessel, thet7 are held in such elevated relation by reason of the lufril being' received in the notch or recess DS. i

The outer end of each stud 1111 is equipped with an anti-friction roller (i2 (Fig.

lil

adapted to snugly lit and travel in a vertical groove 63 (Fig. 9)

on the next-adjacent,

upright bar 32A or 34, as the case may be,

and the cooperation of such roller with the Walls of the groove materially reduces the strain on the other parts of the block. i

To support the lower end of each o the inverted glass vessels 52, the following cooperative inStruinentalities are provided.

.i1-i lower n'icmber 71 (Figs. 8, 9. and 12) grooved at 72 to I'it over the rib 3G, and it is provided, as in the other instanmi7 with a plate 73 equipped with a securing Screw f T4 to c amp member F1 lixedly in any adjusted position on the rib.

In registration with the vertical axsof vessel 52, this support 71, of irregular conformation, has a` split bearing' 75 'for the reception of a stud 76 havingr a circular plate 77 having on itsupper lace tivo, semispherical recesses 7S and 79, about 1S()D apart, as shown in Figure 10.

Oscillatorv on the `fixed shaft or stud 7G lllfi llO above plate 77, a sleeve 81is provided harv i ingr an enlarged, conical head Si). at its upper cud adapted to be partially inf-fertcd in the open lower cud ol thc cylindrical `glass vessel (as shown in Figure l2). the bottoni end, ol auch sleeve harina' a circular plate D?, above and in register with plate T7 and equipped with anoperatingr handle Sil and a seiuifspherical ln'ojcction (Figure adapted to be received in either one ot the cavitiesTS or `F9 to locate vessel 59. in either one Aof two positions for the reception of the two vertical rows of display numerals.

Member 71 has bearings for a horizontal shaft 91 supplied at its forward end with a. turning handle or knob 92 and having;r

teeth cut'v near its rear end forming a pinion 93the teeth otwhich are in mesh with those of a vertically-disposed rack 94, the body 71 being recessed :for the accommodation or' the rack as shown in Figure The `purpose of this raclr-jand-pinion co'nstruction is to permit proper Aand accurate adjustment of the sliding plate 35 in its gicle-ways 34 and the parts which such plate carries.

In order to lock the shaft 91 in adjusted position, it is provided witlra clamp 95 (Fig. 9) between nut 96 on the shaft and the rack 94. j j

By mea-ns of a handle 97 (Figs.` 8 and 12) adapted to turn a short camsha'lit`9'8 having a bearing in the member 71 and equipped with la cam acting on a sliding rod bearing on handle 92 whereby shaft 91 may be forced `loiwvardly causing 'the clamp 95 to tightly engage the rack 94, thus locking theseveral parts in adjusted position.

As in the previous instance in connection with the upper block 41, this lower member 71 is supplied with an anti-fric tion roller 99 (Figures 8 and 9') in the groove 63 of the ne'Xt upright bar.

Each pair of marginal 'guideways 34, 34 has a block 101 (Figs. 6 and 8) slidable therein below the two members 41 and 71 referred to,v and such element 101 is similarly equipped with an anti-'friction roller 102 designed to travel in groove 63 of the next upright bar.

Each rack 94 is lixedly secured to the member 101 in any approved manner and it terminates in a round rod 103 `guided a bearing 104 at the top of the machine (Figure 2) f By means of a connection 105, each rack# rod -103 carries a depending gauge-pointer 106 having an inturned lower end 107 for a purpose hereinafter indicated (Figur`e2).

Each blockl 101 is also supplied with a roller 108 (Figure 8) designed to bear upon and cooperate with one of the movable flexible or articulated membersbeneatli it now about to be described and employed orthe purpose or compensating for the variations or irregularities in the internal size or the vessel to be graduated whereby proper spaces may be produced between the graduation lines and between the numerals associated with suchlines.

Below each of the vertical channels each accommodating the three blocks 4.1,l 71 and 101, I provide a right-angled member 111 (Figures 1, 6 and 7) comprising a gener-v ally-horizontal portion 112 and a front depending part 113. Y

The rear end of element 112 is fixed to an arm 114 havingY a stud 11.5 mountedand capable of oscillation in a bearing 116 on the top of an upstanding arm 117, ferm#` ing part of an inclined, slidable carriage hereinafter described in detail.

Bar 1'12'on one face has ai longitudinal,

dove-tail. rib 118 on which, in the present instance, four (4) blocks 119, 121, 122 and 123 are adjustably mounted and adapted to be held in adjusted position by their one or morel set-screws 124.

Each of these blocks has a vertical, dovetail groeve 125, the fouradjustably receiving four (4), Correspondingly-shaped slides 126, 126,'126ban-d 126.

The vertically-adjustable block 126 has a fulcfrum pin 127 (Figures 6, 7, and 8) se'- c'ured to it and roclringlyV mounted on such pin I provide a slotted end-link 128 forming one terminal element of the articulated or flexible member by means o1 which the upright vessel undergoing graduation is moved along step by step to provide the spaces between the graduation lines.

A pin 129, outstanding from the bar 112, with it-s axis in the same vertical plane as the airis of bearing 116, projects through the longitudinal. slot 131 or link 123 and forms themea'ns around which such link `may turn and by which it is in vpa-rt sup-ported.

It is to be noted that the center or this pin is directly beneath the axis or roller 10S which is in exact register with the axis or bearing 116 soy that any rocking adjustment of the end link under consideration does not influence the position or such roller or the glass vessel. p j

rlhe rear end of the next duplex-link 132 is also pivoted on the 'fulcrum or pivot pin 127, such link comprising two side-plates straddling tlie' intervening end of the linlr 128 on the pin` 127, as is clearly indicated in Figure 8.

y rFliese two plates constituting a portion of the link 132 are grooved 'on' their inner races at 133, 133 to accommodate the longitudinal yribs 134, 134 on opposite sides of a middle slotted link-member 135 positioned between the plates 132 and having a'. sliding engagekment therewith, so that the linl; 132, as a whole, may be ,lengthened or shortened as required. y l

rThis flexible or articulated member, comprising the several jointed members, has the pivotpins 127, 141 142 and 143 Lmounted on the slides 126,l 1262 126b and 126, respectively, and pivotally connecting together the extensible and contractib'le links already described and also' those characterized as a whole 144- and 145, which are substantiallyv of the same construct-iones the Aothers but or different lengt-lis, as is clearly shown in Figurev ,6. v

The sereral links unitedly constituting the'v flexible member are or progressively greater length, as depicted in Figure 6, be-v cause the vessels to` be graduated vary in v internal caliber more near their bases than elsewhere,` hence requiring shorter links to actau'ately compensate or cminterbalance for such variations in the spaces between graduation lines.

Outside of or beyond the link members described as mounted on the pin 127, I pros ride a pair of links 151, 151 (Figure 6) the lower ends ot which at 152 are pirotally connected to one arm o1'I the bell-crunk lever 153 fulcrunied at 151 to an extension 1:35 ot the block 119, the other arm of such bellcranlc lever being pivotally connected at 156 to a rod 157 haring a threaded end portion 158 extended through a hole 159 in the part lh such rod being equipped with a threaded nut handle or knob 161 by means of which the rod n'iay be adjusted, a coil spring 162 encirclingr the rod between a sleeve 163 and a collar 164l slidably adjustable lengthwise on the rod and held in place by a set screw, not shown.

lft will be understood from this construction that. by n'ianipulation or turningl ol handle 161` the fulcrunrpin 127 may he raised or lowered.

The three other pivot-pins 1el-1` 1-l-2 and 143 are similarly vertically adjustable by like constructions equipped with nut-handles 165` 166 and 167.

The overlapping ends of the several link elements are rounded concentrically with the unes ot the pivot pins as shown in Figures 6 and 7, so that there may be no abrupt projections along the top surface of .such articulated construction.

The iront end oi each member 112, 1123 is supported on the inclined. sliding carriage rel-'erred to by means oi aY telescopic, lengthwise extensible and contractible rod 171 (Figures 1, 2 and 6) having trunnions 172 near its lower end accommodated in seats or saddles 173 on the sloping carriage mens tioncd.

The upper end ol this supporting or brace rod 171 is pivotally connected to one arm oi the bell-crank lever 171 fulcrumed at 175 on the member 112, the npstaudinsr arm ot the bell-crank being in contact with an adjust-ment screw 176 having threaded engagement with a hole through the top portion ot the element 113.

lft will be clear through an umlerstanding ol' this cinistruction that the position ot' the member 112. 1123 may be Varied either by reason oi an extension or shortening ol the rod 171 or by turning el" the adjustment screw 176.

In order to relieve, in parl. the weight ot' the several. Vertically-slidable plates 35 and the elements which they carry, there is attached to each a cord or cable 181 (Figures 1 and 2) extended over a pulley or sheave 182 ou a shaft 183 at the top of the machine. a rear, depending end of the cord or cable being tit-ted with a weight 184., notI wholly neem/ie counterbalancing the weights o1 the parts on the other end ot the cable but relieving the load imposed on the carriage and its series of articulated members.

Referring now to the inclined, screwactuated, intermittently-operated carriage 191 previously mentioned, it will be observed thatyat each end. such carriage has two rollers 192 and 193 (Figure 6) desigg'ned to travel on the top face ot' inclined bars 191v forming parts of the mainframe, the lateral sliit'ting of such carriage being prevented by rollers 195 bearing on the outer tacos ot such sloping supports 194, and rollers 195" cooperating with guitfle-bars 195" (Figs. 1 and 6). l i i The weight of this oblique carriage is more or less counterlnilanced by one or more weights 196, each on a cord 1.97 connected to the carriage and passing over a suitablysupported pulley or sheare 198 mounted on the back part o'll the mainframe.

Such inclined carriage, on which are mounted the plurality ot flexible or bendable members co-acting with the supports for the rcssels to be graduated, is fed upwardly by a pair of appropriately-supported, sloping screws 201, 201 (Figures 1.l 2 and 6) the lower end of each of which has a ball stepbearing 202 (lfigure 6), the upper end hay ing a suitable bearing as shown in Figure 1.

ln a construction ot this character, it desirable not only to feed the carriage upwardly by the intermittent rotation of these screws, but also to permit the sliding oi the ari-lage on its supportsindependently on the screws and accordingly the machine is equipped with the following, co-operating, mechanical elements.

As is shown in Figures 2, 6 and 11, the carriage for cach screw is supplied with an outer, semi-cylindrical bearing 211 in a block 212 fixedly mounted on the carriage, and opposite this and guided in its reciplo cations by the carriage itself and by a supplemental bar 213, I provide an innerhal'fnut bearing 214, which may be reciprocated into and out o1 cooperative relation with the corresponding feed-screw 201. y y

then the two half-nuts are up against the screws, as shown in Figure 11, the carriage will be athfanced when the screws are turned, but` when the half-nuts areretracted it'roln the screws, then the carriage may he slid Afreely lengthwise olt the tliclnslzatiormry leed SCI'VS.

Oli course. these two half-nuts must be actuated simultaneously, and, accordingly the two are joined together by means of links 215 and 216 connected to the opposite ends oi an arm 217 (Figure 2) centrally mounted on an inclined shaft 218, square or angular in cross-section, and oscillatory in suitable bearings, one of which 2197 is indicated in Figure 2.

lun

Ll (l of the machine between tivo blocks 22S-andv 229 (Figure 1).

By manipulation Vot this handle, the tivo half-nuts can be easily shift-ed into and out` ot coactive relation with the pair ot inclined reed-screws.

We will now turn vto a consideration of the construction yof the means for interruptedly or interniittently rotating suchl carriage-eeding screws, particular reference being had to Figure 3.k

At its uppery end each such inclined screwshatt hastastened to it a ratchet-Wheel 231, and free to rotate on the screw-shaft adjacent to the ratchet-Wheel is a segmental-gear232 having a radial arm 233 equipped With a spring-actuated pa\vl=234 adapted to cooperate with the notches of the ratchet-Wheel, the latter being also supplied with a springactuated retaining paWl A235 adapted vto pre' vent overthrow.

The teeth of these two, fragmentary gears are in mesh with those ot a .slidingly-mounted rack 236 constructed toA reciprocate in suitable bearings on theY rear, inclined .portionot the machine trame.

Such rack is slid back and forth by means of a bent link 237 pivotallyconnected at 238 to one arm of abell-crank lever l239, Which may be ulcrumed in .a casing 241- at any one of three points v242,243and 244, de-` pending` upon lwhich registering holes yare supplied with the fulcrumpin 245, the latter being capable .of insertion in any one of three holes to vary or modify the `extent ot' the stroke `ot the link 237., which determines the degree ot the turning action of the ratchet-Wheels by `the pawls.

The otherend of link 237 isr tulcrumed at 246 to a block 247, slidable beneath an apertured plate 248 mounted on and spaced troni the rack 236 by .means of two, end, supportig and spacing blocks 249 and\251,iblock 247 being normally retainedrbetween member 251 andtheadjacentend-ot` an arm 252 tulcrumed at 253 andv ordinarily pulled upwardly by a spring 254 yfastened vtoapin 255 projecting from plate 248 and its other end to a lug 256 onthe arm252 and extendedupwardly through aperture 257 in plate 248, .such lugl carrying an anti-trictionroller 258 designed to coact with a `cam Vbar`259 on an approximately-mounted rock-shaft 261, the Yrack be ing recessed. at 262 'for the reception of the arm 252 when it is depressed by thecam.

Thus, normally, the link 237 is .in direct pivotal connection With the rack Which it reciprocates, but because of the marking of vceptacles undergoing graduation.

each tenth graduation line around the` vessel being gradluated, it rs necessary to permit an idle stroke ot the block 247 yat that time, and, under such circumstances, the arm 2521 is held vdepressed by the oscillatory cam 259, so lthat the block 247 reciprocates over it rather .than operatively bearing against its end.

The bell-crank lever 239 is rocked by a ylink 263 having a bifurcated `or forked upper 'end straddling and actuated by an eccentric 264 on a suitably journaled shaft 326 (Figures `1 and 2) revolved through gearing 260 4by the main drivesshat't 265 supported at its outer end in a bearing on abracket 266.

Suchdrive-shaft is rotated by means of a pulley 271 thereon andan appropriate clutch 272 and its yoke-lever 273 .which isconnected to the other side 4of the machine by a link 274, (Figure 2) referred .to hereinafter, and Which is automatically operatedvto. stop .the machine by' throwing out .the clutch, when the final graduation lines-have been made.

By the means described, the .pair ot inclined, vparallelscrews are turned intermittently or step by step causing a correspond` ing, upward rearwardly-sloping travel of the carriage on Which is mounted theplurality of flexible members governing `the upright travel of several vessels or Considering now the scriber or marking mechanism `for making or scratching the graduation `lines :in the Wax on the several vessels, it will be sutlicient to describe one of these in detail, -because they are all alike, and one description will `b e adequate for all.

Across the front of the machine and fastened to its trame is a 4bar 275 (Figures 1 and 2) having a'plurality of vertical cylindrical apertures 276, corresponding in v number to and adapted to receive the vessels to be graduated.

Eachsuch aperture constitutes a bearing tor a sleeve'277 (Figures 13 and 14) having external gear-teeth 278 around its periphery;

these several gears and their sleeves being' rotated in synchronism 'by lspiral-gears 279 on a shaft 2,81 having a gear 282 on its end revolved by means hereinafter described.

l@n the top edge ot each one ot these sleeves 277 va sharp-pointed `scriber or marker 283 is rockingly mounted at 284 'and' itis equipped with a tail 285,'a coil-spring` 286 tending to rockthe scriber toward the vessel to be marked or graduated extended through thesleeve 277.

Inasmuch as these scribers, which rotate around the glass-vessels are to make some graduation lines thereon extending only part Way. around the vesselsfit is necessary to provide means, at the lproper time. to shift the scribers away from such vessels, and, accordingly, the top edge of each sleeve 277 Complete-1y glass reh llU is provided with a roel'arin 291, t'uleriuned at 292, and Carryinga supplemental arm 293 roekingly mounted thereon at Q94, such aux liary arm overlapping the srriber tail being adjustable on the main rook-arm E291 b v set-screws 295 and 296.

The lower end ot the tuleruni-pin 291i Carries a narrow, anti-triction roller 297 de- Ined to cooperate with a plu1"alit}r of ioaliyauljustable calins to modify the action ot the seriber or marker on the glass vesseh that is to say, to cause it to a pproaeh or recede 'troni tl i nlasswessel.

The srriber-eontrolling' earns referred to, in the present instante,l are :tour in nunibeny :luk 2502, :lol-l and lll-ll'or each seriber und vessel. sui-h Canis being' (f-,oneentrieally nuuinted in au aperture in a plate 305 (Finurea l, :2, l2. lh 1G, 1T, 18 and 19) located above the bar 275, this plate, of course, have ingr as manhvT sets ot' earns as therA are scribers on the inaehine.

Assuming' that the glass ve; el now plzu'ed in position readyv At'or marking` the roller 29T, governing: the approach ot the seriher to and its reression t'rorn the vessel, travels around on the surtaee ot' the relatirely-stationeri7 eain 301 until it reaches the depression in the (fain, at which time the seril'ier approaches the vessel aud begins to uuu-k the graduation line.

Then the plate 305 raises the cani 303 into the path olf the roller Q97, this being the cani which is used lor inarkii'ur the unit lines (see Figure 17).

The seriber and roller eontinue torevolve around the vessel marking; the required number of unit lines, a iter which plate 805 is elevated still higlier bringing cam 304; into the path of the roller Figure 118) for 1narkine' the iil'th line which is somewhat longer than the unit lines.

Then the plate 305 descends again to the unit line positiijin making', in this ease, tour additional unit lines, whereupon the plate is shifted bringing cam ring' spacer 30:2 opposite the roller (Figure 15)) lior the niarkinler of a complete `,erzuluation ring?r around the vesieel tor eaoh tenth line,

ln mai-kine` sueh tenth ringe' or line arouiul the article undergoing graduation. the seriber or marker 2G25 is brought against the vessel by the unit-line eain, then innnediately after startingy the niark, the plate 305 brings the second cani :502 into action, and then the tiret cani, juist as `the depression ot the tirst can] is in register with the roller, this tenth-line niarking operation taking just a little more than one Complete revolution ot the roller.

The soriber is then retraeted elear ot the vessel and the balance oiI the revolution is idle and the sorenr airain aiilwinees` the earringe for the next unit line.

During' the extra revolution of the soriber or roller, that is during' the marking ot the ring;r completely around the vessel, the earw riaee is not advanced by reason of the depression oif arm 252, explained before, but during the next subsequentlyidle revolution ot the seriber, the vessel is advanced one step to the next unit line position.

Thum it will, be perceived, that the seriber or marker makes eleven revolutions around the vessel for the nuikingr olE eaeh ten lines.

ils has been indicated above, the omission ot one advance step ot the carriage tor eaeh ten linesl is brought about by the desi-,ent olI cam-arm i259 into the path ol travel o l the roller 25S, the meeluiuism tor accomplishinel thisaetion eonuirisinel the following parts, particular reference beinghad to Figure el.

Shaft 261 has an armlil thereon eon neoted by a. link 332 to one arm of a bellerank lever 333 tulerumed on the traine at 33% and having a roller 335 enacting;r with a suitably-sluiped Cain 336 on shaft 321?) beside Cain 322. i.

It is desirable that the seribers or markers should approach the vessels to be graduated and should recede therefrom comparatively slowly so that the beginnings and endings ol the graduation lines may be in exact register, but to econolnize on time, the rotation ot1 the soribers duringr marking operations and their idle partial rotations is at a much higher speed by the improved meehanism `of this machine which accomplishes this result ,advantageously and effectively by cooperative mechanical elements `abont tobe described.

It will be remembered that the scriberrotating shaft 281 has a. gear2j82 (Figures 1 and 13) which is in mesh with a larger gear 341 on a jack-shaft i342 furnished with an lelliptical drive-gear 343 meshing with a sin'iilarly-shaped gear 344 onshaft 326, and by this means the specified, desirable irregular rotation of the several scribers is brought about.

The inclined, sliding carriage should be capable of movement otherwise than by its two feed-screws to shift .the flexible elements, which compensate for the irregularities in the internal calibers .ot the vessels to be graduated, to quickly move the vessels to different points corresponding to preliminary gauge marks on the vessels, whereby the flexible. ,elements may be properly individually adjusted to. accurately perform their functions, and to this vend the following` parts have been provided in this machine:

At its two sides .the sliding ycarriage has two, inclined ratchet-,bars 351, ,351 (Figures 1 and 2), secured thereto, and, across the back .of the machine, I supply a properlyjournaled, hollow rock-shaft 352 (Figure 1) having vfastened thereto two arms 353, each adjacent to oneot` .the ratchet-bars, and .on the end of each such arm I .pivot at .354, a .bell-.crank pawlg355, one arm of which acts as a latch to co-act with the ratchet-bar, the other arm having a leaf-spring 356 connected vthereto at one end, the A.other end being mounted `on a lever 357 fulcr-umed on the side ot the arm 353 at a. point 3 58,this armhaving a bearing at one end'v on a. shaft 3,59linside of the hollow shaft 352. n

A bent handle lever 361 is secured 11o.. one end ot the hollow shaft 352,.and= an `anni 362. secured -to a :protrudin end of the inner shaft 359. is connected y a link 363 to an auxiliary handle-lever 3.64 tulcrumed on ,the main-handle at 36,5, a. coil contractile spring 366 connecting parts 361 and 36,3, as .shown in Figure 1.

A belt-.crank-holding-pawl 371 (Figure 1), one of-whichis pro-vided for each ratchetbar, fulcrumed onl they main-frame at 372, has a V-sliaped .end receiving a springpressed plunger 374 on an varm 375 rockingly mounted ,on the main-frame at v37.6.

Each arm 353 at a point 381 has a bar 382 pivoted thereon, such bar being slidingly associated with the corresponding rockarm 375 and having two, spaced pins 383 and 384 on opposite sides .of land oyerlappiug the edges of the member 375. l/Vhen it is desired tot slide .the .carriage upwardly by the mechanism illustrated jand described, vit is merely necessary to raise handle 361 the desired amount and the locking pawls 371 will rideOYer the teeth ot the ratchet-bars and automatically `tall into the .desired notches, retaining the ratchetbars and carriage in the new position, and this operation may be repeated as many times as is desired.

lVhen, however, the .carriage vis to be shifted downwardly step byv step by this hand mechanism, the operator, by actuation or the supplemental-handle 364, releases the pawls 355 from their respective notches, and, thereupfm. by raising handle 361, permits the pawlstov engage new and more elevated notches, but before the carriage can be permitted to descend the pawls 371 must be released from their notches.

To do this, the operator continues thel upward raising vof the lever A361, and when pins 3.84 pressagainst the sides ot arms 375, the two pawls 371 are retracted out of their notches, permitting the operator to let the .carriage descend, the handle 361 vand pawls 355. by this time being in the notches referred` to.

As soon as the descent is accomplished, the pins 383, by engagement withthe other edge of the arms 375, will automatically canse the holding pawls 371 to enter the new notches and locate the. carriage in the new position, n

This lowering operation may be reproduced `as many-.times'as is necessary.

Turning now to that portion of the mechanism that marks the numerals or graduation figures on the glass -vessels opposite certain-k pre-determined graduation lines, as shown` lior example in Figures 25 and 26, it will be perceived that the 'machine inclu-des. a relatively-long vplate 391 (Figures 1, l20 and-21) ,equipped with. six pointed or needle-like markers 392` lwhich are yieldingly .pressed inwardly toward the glass vessels by leaf spring mounted on the plate.

At its two ends, this plate is supported ou up right, len gthwise-adj ustable sust a i ningrods ,394 (Figures 1 vand 20) which, at their upper ends, are mounted on a pair ot forwardly-projecting arms 395, 395 on a shaft l r 39.6 rotatably supported vby anti-'friction roller-bearings 397, 397. f

Sha-tt 396 is equipped at one end with a rdepending arm 398 connected at its lower end by a ball-and-socket joint 399 to a link 401, the other end of which is associated by a similar joint 402 with an upright bracket 403,11ockingly mounted on the main-trame at 404.

`This bracket carries an upright rod 405 on which is adjustably mounted a block 406 having a ball-and-.socket joint connection 407 with a. link 408, the opposite end or" d ll which has a like connection 409 with a block e111 similarly vertically adjustable on an upright rock-shaft 12 oscillatory in suitable bearings.

The lower end ot the shaft 112 has a block #ii-1&3 (Figures 21 and 22) provided with a universal-joint connection -lll with a llorwardiy-eidending arm Lll adjustable as to length and carrying at its trent end on its top a manipulating knurled knob L16 (Figure 20) and on 'its under surface a pointer or needle elli' designed to co-act with the several, engraved. numeral recesses @L18 (Figure nl) on the round, centrally-aperturcd, inascr, marking plate 419 adapted to be turned around the axis ot a round portion -lz'l olf a supporting bracket- -lll to bring an)T one ot the master numerals into operative posi tion, in which relation it is held locked by a catch 1l-:l2 on a cross-bar 423 designed to enter any one ot the plurality ot locking recesses @el on the plate 119 and corresponding in position to the several engraved numerals, and it will be understood that, as the tracing-pointer -l17 caused by hand to travel around the numeral grooves or channels` ot the plate slit), bar 15 will be moved backwardly and 'forwardly and also sidewise during such opiration.

The remainder ot the mechanism tor causing the markers 392 to travel in paths correspondingl to that ot the pointer or stylus i-1i' tor the marking and numbering simultaneously ot the several vessels will now be described.

The universal-joint construction 14 is also connected to a back rod ll which at its other end is bifurcated at 432 (Figures 2O and and is rockingly mounted on an upright, stationary shat't 33 supported in a lixed bracket #i3-l, the axis ot' the shaft 433 :,'oin-:tituting the center around which this coniparatively-long rod L ll turns.

ltockiugly mounted on the stationary sha't't 433, lY provide a bracket 435 having adjustably tilted to .its lower end a forwardlyinfojecting arm -l-llf. the length ot which may be varied and the arm held in an adjusted position in any approved manner, as by tightening screws -l-li', the tree end ol arm 136, by a ball-and-socket joint 43S, being connected to a rod 43S), which, at its opposite end, by means et' a similar ball-and-socket. joint tri-l1 (Figure is associated with a collar adjustable lengthwise on the part 1415, the rod -l-ll having a telescopic adjustable connection so that its length may be varied.

The oscillatory bracket Li535, at its upper end, has a forwardly-extending arm 451 (Figure 21) which, by means ot a ball-andsocket joint 452, is connected to a rod e153, iapable ot variation as to length, and pivotally connected at 454 to a lever -lr'i t'ulerumed, by means ot a ball-and-socket connection 4,56 on an inwardly-extended lug on the lower end of an arm 457 fixed to one end ot' a suitably-journaled sha'tt 4.58 (Figures 2 and 20) the iront end ot the lever being Iioined by a ball-and-socket connection with the corresponding end ot' the plate 391.

At its opposite end shaft i1-58 is supplied with another arm 455) (Figure 20) oi the same length and same angular position as arm '-l-S and connected to the corresponding end otA the plate 391 by a bar toll having balland-socket joint connect ions with cach of the iliarts tot) and 391.

In order to be able ioniove the plate $1391 and its several marking needlesl out oi the way and out ot contact with the glas#4 vessels when desired, a handle lll (Figures :f1.0 and 21) is mounted on and secured to arm 4h37, and it will be apparent that by moving this handle, through the mechanism described, the plate 391 can be shifted for the purpose indicated, a catch 4:59 on arm da) being adapted by engaging a recess 4159 in the trame to hold the parts in the position to which they have been moved by the handle thus maintaining the scribers or markers clear ot' the vessels when setting the machine tor marking, thus avoiding unintentional scratching ot the coated surlaces ot the vessels, a set-screw -loir being also provided which by cooperation with arm 4:59 prevents the bar 391 trom accidentally striking and breaking the vessels.

lt will be readily understood, that, as the tracing-pointer 1117 is moved backvfardly and forwardly horizontally, it rocks the upright rod Li12 in a corresponding direction and this movement through the parts 40S, 402%, 101, 398, B96 and 395 is translated into a vertical movement oi the scribers 392, such movement being proportional to, but not necessarily equal to, the corresponding movement ol the traciiig-needle -l-li.

By adjusting the position ol the link 1:08 up or down on the rin'la 4.05 and Ll-lf2. a greater or lesser leveriure is secured, and a vvariation in the heights oi the scribed uumerals can be easily el'l'ectcd, it beine; apparent that the sizes o l: the nuinerals should ordinarily be proportitnnil to the sizes o the vessels undergoing graduation.

The cross-wl. ,e movements ot the tracing needle ot pointer ulli7 'euses horizontal, lateral oscillations ol'v the arm gi-15, and these are transniitted through the link 41:39 to the oscillatory bracket 4135, and iroln the latter through the parts 451, e153 and to the plate 391 and its several ecribers.

The variation in the widths o't the minierals may be effected by merely adjusting` tbc length ot the arm lli-SG, so that numerals oi any reasonable width may be marked on the glass vessels hv the use ot the single masterplate 11:19.

l i H fil) The position of shaft 433 maybe different from that shown, if preferred, to modify the shape or general character of' the numerals marked on the vessels.

lt is desirable to stop the operation of the machine after the final graduation lines have been marked, and to accomplish this result' i" 475 connected by a. link 47 G to a hook 477 pivoted on a long latch 478 having a ful-l crum-pin 479 slidable in a slot 481 of a. link 482` pivotally joined at its front end to a rockingly-mounted, forwardly-extended handle483, and in like mann-er connected at its rear end to one arm of a bellcrank lever 484, the other arm of which is connected by the rod 274 (Figure 2) to the clutch-lever 273 (Figures 1 and 2).

Manipulation of handle 483 will throw the clutch into and out of operation by the means described, but inorder that it may be'shifted to stop the machine automatically when the final graduationlines have been made, afiXed lug or abutment 485 is provided on the frame of the machiner with which a notched end of the catch or' latch 4.78 is adapted to cooperate, as shown in Figure 1, the short arm of such catch being.

'i connectedby a. coil, contractile spring 486 to a pin 487 on the main-frame.

lVhen the handle 483 is turned or rocked to put the clutch inoperative position, the right-handfend wall of slot 481, by engagement. with. the pivot-pin 479, forces the catch to the left against the-action of spring 486, as shown in Figure 1, until the hook end of the latch springs up and bears against the lug or abutment 485, in this way storing power in the strained spring 486, but, owing to the slot connection with the fulcrumpin of the latch, the clutch` can at any time be throwninto and out of operation by the handle;

lnorder to release the clutch automatically after the marking of the final graduation lines, the shaft 323 is equipped with a cam projection 487 (Figure 1) normally revolv ing .out of contact'with hook 47 7, but when cam 471 on the carriage, by contact with the roller 472, rocks thefarms 473 and 475 upwardly, it carries hook 477 into the path of travel of the projection '487 so that at the proper moment the latter' engages the hook and rocks theA latch 47 8; downwardly away from the abutment 485, whereupon contraction of the spring 486'pulls the link 482 to [he right, as viewed in Figure 1, throwing the clutch out of action and stopping themachine.

The machine is operated substantially as follows: f

Assumingl that the siX glass vessels to be simultaneously graduated have been externally coated with a suitable, etching-resistant material, such as waX or paraffin, and by means of accurate measured amounts of liquid' have been provided by hand with short test-marks made with paint or ink on the glass vessel before being coated with the wax corresponding to certain, pre-determined, graduation linesfor example the Second, twentieth, fiftieth and hundredth lines 'from the bottom of the vessel, corresponding, for instance with graduation marks -200-500`and 1000, and, assuming further that the several vessel-supporting blocks 41and 71 in the plurality of upright channels or spaces have been adjusted on their respective slides at proper positions for the reception of vessels of the sizes to be graduated, these several glass-cylinder graduates or other vessels are inserted in inverted relation with the parts 82 in their open mouths and the top clamps are turned down to lock them into place.

Then, after unlocking the several knobs or handles' 92, by turning the locking handles 97, these several members 92 are turned individually to bring the first test line on each cylinder-that is, the test line nearest its enlarged base-exactly into register with the corresponding index or pointer 107 This insures that the test line will be eX- actly in register with the pointer 107 when the roller 108 is on the complementary portion of the flexible or articulated member which is to cause theA lengthwise travel of the vessell during graduation.

rlhe several glass'cylinders to be graduatedl were inserted inthe machine just after the latter had completed the graduation of the preceding set of`i`vessels and the appliance is in its hundredth or final graduation line position, and the turning of handles 92, to effect the register above specified, was done when the above-mentioned glass cylinders were in final line position. 4

It is now necessary to adjjust the plurality of articulated members corresponding to the final or hundredth line position for each of the glass vessels and for this purpose the top surface of the plate 391 is used as a sight-gauge when the tracing pointer 417 is located in a fixed-depression 491 in stationary bracket 421 which gives a definite location as to the height of the plate 391.

Each screw 176 is turned to raise or lower its entire flexible mechanism until the hundredth or final test or gauge mark on each vessel is exactly inregister with the top surface of the plate 391.

Atthis time each roller 108 will be substantiallyv above the axis of the corresponding pivot-pin 142, or, if preferred', suchl zuljustinent might have heen made by inanipulation ot' the handle 166, or of the two handles llil and 176, conjointly.

'lliereupcm the operator, a'liter releasing the two halt-nuts hr handle 227, hy means ot the lever Stil and its` associated auxiliary handle itil-l, lowers the carriage down to the ,ilteth line position at which time the axes el? rollers 105i will he inactically ahore the axes ot the pirot-pinsI lll, and then the workman turns the knohs or handles 165 in dirii'huilliV and in succession to bringeach test or gauge mark ot the Ii'l'ticth line pouitien on the reesel into intact register with the top surlaec ol' plate lll.

llcxt. the operator, hy ultramY ot handle Iltl and ita suppleinentar)v handle Stiel, feeds the carfiagre down to the twentieth line position at which time the axes of the rollers illu will he approximately ahoi'e the axes of the ciwrespondilnr pivot-pins lili' and he turns the several handles lill to adjust the pos-ations: ot the vessels ao that their twentieth-line test marks will eactl)r register with the top surface of plate Bill.

lt may ire reniarked in passing, that the other pivot-pins lll-3 and their links are used when more than one hundred `araduation lines are marked on the vessels, or provided a greater number ot test marks are (nin'inalhvr placed on the Vessels.

rlhc carriage is now shifted to the tenth line position and the operator, hy means oi" knoh lill and that. member on plate 419 hearing;l the numeral 100, traces such engraved numeral with the stylus all?, thereby marking a 100 ol appropriate size at the tenth line position on all six otl the Vessels elmultaneoualr (eee Figure 25).

Then he shift` the carriage to the t-wen tieth line position and places the immoral "300" on all oi the vessels at the naine time, and hrcontiuuei-s this operation until he has applied the entire ten numherslllil to llllltl'f' inclusive,

This ia all done while platea 83 are held in one of their two positions with the de lents in one olE the rtu'essee` 75l or Tl), afsaurinpa .straigrfht line oll displayr numerals :scratched through the 'ax coating' on each Vessel by its sharp marker 392.

litter thie` has` heen completed, all six of the plates` Sil are shifted h v means olE their handler: ttl until the detente S5 are in the other recesees T8 or T9` thus turnin; r all oli the pjlass vessels on their own axes approxi mately,v ,180".

Now the operator, hy the means previously deaerihed. simultaneoushv places the numerals zero O in the new rows oi tigurcs l'or the `ajradnation lines (not yet n'iatle) ,larthcat from the hases and then feeds the resrels Step hy step and in sequence applies the numerals 100 to 900 inclusive, all of which compensate for the irregularities in the internal calihers of the vessels even though their nuirkinpis on the Vessels occur simultaneously.

The operator in at this time ready to appl)7` the `afracluation linea` on the vessels spaced apart varying' amounts compensating; For a like 'ariation in the internal calihers hy means ot the articulated men'ihers.

lt will he oliscrred that the links of these articulated members corresponding to the lower portions oi the glass, resale are slmrtcr than the other linke and, as; referred to above, this is due to the 'tact that there is likely to he a gri-rater variation in caliher in euch portions oi the ii'essels hence requiring' more accurate compensation in the `erzuhiations.

The carriage hy meant` of' handle Stil is lowered to the unit line position and handle 22? is then rained to shift the two half-nuts 52M into operati re relation with the two feedscrews h whereupon, hy means et handle S1-l, the clutch 272 is rendered operative, amil, at the same time, latch 4.78 is carried rearwardly straining' spring 486, and caused t0 overlap and hear against ahnt ment 485, which maintains the latch in this retracted position. o

Then, the machine automatically marks spaced graduation lines ol dillerent lengths on all of the vessels at the sametirne, the unit. lines being ol one length, the fifth lines somewhat longer, and the tenth lines extendina;r entirelliY around the vessels.

To make up Llor the longer marking ol such tenth lines, during; which period the Vessels must not more lengthwise, the cam 25S) is automatically ehit'tcd into position .Lio that duringl the produ tion ol' such tenth linea there is no movement oli the rack 3BG to operaie the carriage 'e ul-:-;e.1'e,w.s.
